I can only speak for myself, but my problem with Season 2 wasnt that they were in one location, but that they told the same story repeatedly for several episodes. There are only so many variations of "where's Sophia? Let's look" and "Get off my farm! No ok you can stay. No, get off my farm!" before it gets stale.
Hopefully they'll do a better job in the third season, and not use a static location as an excuse for keeping the plot static until the last few episodes.
Yeah while I really liked all the main story beats they hit on the farm, it did get awfully repetitive and drawn out at times.
It didn't help that things seemed a little TOO calm and serene there. The longer and longer they stayed, the more it strained credibility that they weren't discovered by a zombie hoard.
what I didn't like about the farm is the show was totally lacking any insight into what is going on in the rest of the world. Now that the season is over though I like the juxtiposition of the serenity of the farm and complete vulnerability they are facing now. They have no supplies at all.
btw, why aren't they finding cb radios and trying to contact other survivors that way now?
